1877.— Berries of Berberis Darwinii

July 31' 8˚

Finally compared berries of which 10 were cleaned on the 15th & 10 not cleaned & since syringed.

Of those with bloom, the juice of 8 was still purple & of 2 brown

Of those without bloom, the juice of 3 were purple, but rather dingy; 1 which cd hardly be called purple or brown; & 6 decidedly brown with no tinge of purple showing great decay — I have now squeezed all 6 on paper & let juice dry; not one of those with bloom removed has bright red or purple such as the old as that of those which had not been cleaned; & the one half & half, has only a tinge of purple.

N.B The pistil remain adherent to fruit& the lower part coated with bloom as on fruit.— not so the peduncle. —

July 22d 9˚ 5' cleaned with damp sponge (so advantage this way) 6 ripe berries of Berberis Darwinii & put other 6 in same saucer to see which will dry first

July 25' 8˚. — 3 of cleaned berries are somewhat shrivelled.

July 26 8' all 6 of cleaned berries are shrivelled though one of them only slightly; & now of those with bloom 2 are shrivelled.—

27th 8˚ all of those with bloom are now shrivelled except 1.

The cleaned berries more deeply wrinkled.)

Berberis Darwinii (in my Study)

July 15. 12˚

cleaned of beautiful bloom with bit of sponge & water at 80° to 10 ripe or nearly ripe berries, but their surface were still water repellent & put in little saucer & slightly syringed, so that a very thin layer of water lay at bottom. —

10 other berries not cleaned treated in exactly same manner; water shoots off them beautifully— & after hea sharp shower not a drop on the perfect ones.

(July 28th much mould about the cleaned berries & water much dirtier, seem much more rotten.)

July 29th 3 of the cleaned berries now shrunk, mouldy & rotten; juice of one brown)

(10 berries not cleaned & not watered & left in dry saucer

July 20th 8° all greatly shriveled.

July Plate got so wet put on Blotting Paper
